I think Rjio has already missed a large opportunity to airtel and now to other if they start before rjio.
The only way rjio can stand a chance, if service is exceptionally well (which i doubt, as ii 2300mhz deployment cannot give you bestcoverage. And they dont have 900/1800 in every circle) secondly they come on dirt cheap prices (which by all means looks to be the market strategy to gain customers).....
Else i see rjio going in history like kingfisher airlines...people will read about it on wiki ....once thr was a company who tried doing this .... But couldnt sustain..
